Kim Kardashian has postponed her baby shower following Lamar Odom's recent hospitalization, her rep confirms to ET.
The celebration in anticipation of Kim and Kanye West's second child was scheduled for Saturday at the home of family friend, Sharon Azoff. The Beverly Hills estate owned by Azoff and her husband, music mogul Irving Azoff, is also where Khloe Kardashian and Lamar Odom were married in 2009.
The baby shower was supposed to be thrown by Kim's sisters and filmed for their reality show, Keeping Up With the Kardashians.

The reality show cameras have not been rolling in Las Vegas, where Odom remains in critical condition at Sunrise Hospital. The 35-year-old NBA pro has been visited by his estranged wife, Khloe Kardashian, and her sisters -- Kim, Kourtney Kardashian and Kylie Jenner -- and her mother, Kris Jenner, as well as Odom’s ex-girlfriend, Liza Morales, and their two children, Destiny and Lamar Jr.
A source tells ET that there have been encouraging moments. Odom briefly fluttered his eyes open at one point, and Kim believed that he also squeezed her hand. Still, ET is being told that Odom's kidneys are a top concern, as they have reportedly started to fail, requiring him to be placed on dialysis.
